Chess Opening Theory/1. e4/1...Nc6/2. d4/2...d5

= Nimzowitsch Defence = To face the central tension, White has three options :
 * /3. e5/ closes the game. The pawn structure looks like a French Defence without the blocking Black's light square bishop.
 * /3. exd5/ simplifies the game, but won't prevent Black from playing e5.
 * /3. Nc3/ increases central tensions, which can be released with 3...dxe4 or maintained with 3...e6 (transposing to French Defence).
